How to install a union ball valve?

[Gary Ellis]

I want to install a union ball valve on my return to a Clarisea. Which way should the arrow point on the valve? Thanks

The arrows on valves point in the direction of the flow.

Pretty sure you want the arrow pointing towards what way the water flows
